The Claim

An acute bout of resistance exercise in rats is associated with robust but transient increases in mTORC1 signaling, including 26-fold higher p-S6K1 and 5-fold higher p-S6 at 6 hours post-exercise, returning toward baseline by 48 hours.

Source: Myofibrillar protein synthesis rates are increased in chronically exercised skeletal muscle despite decreased anabolic signaling

What the research says

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

When rats do a short, intense workout, their muscle-building signals spike a lot right after but fade back to normal within two days.

What the research says

1 study

  1. Study: Myofibrillar protein synthesis rates are increased in chronically exercised skeletal muscle despite decreased anabolic signaling

    The study did the same exercise in rats as the claim describes and found that the muscle signals went up a lot after 6 hours and then went back to normal by 48 hours, just like the claim says.
